Remove support of OSS without extents

Improvement Minor Closed Won't Fix Artem Blagodarenko Artem Blagodarenko Fri, 24 Mar 2017 12:01:58 +0000 Mon, 1 Oct 2018 08:29:19 +0000 Mon, 1 Oct 2018 08:29:09 +0000 0 3 <p>Artem Blagodarenko (artem.blagodarenko@seagate.com) uploaded a new patch: <a href="https://review.whamcloud.com/26177" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/26177</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-9253" title="Remove support of OSS without extents" class="issue-link" data-issue-key="LU-9253"><del>LU-9253</del></a> osd: no support for indirects<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 9ee69946e7f98bdd8865d7d982583db1ea5e4491</p> <p>The main question isn't whether we format new filesystems with extents, but rather whether any filesystems exist that have block-mapped files for some reason? For example, we format the MDT without extents, and it has regular files (llog and OI files). Also, with Data-on-MDT the MDT will start doing bulk IO, so I think this patch would break the OSD code. </p> <p>Andreas gave good reason to not delete extents support on OSS. I am closing this issue.</p> Development Rank 1|hzz87r: Rank (Obsolete) 9223372036854775807
